@marioguzman I could be wrong, but I think it does this because its windows are not AppKit; it still has some Carbon code from its SoundJam / iTunes origins. It bugs me too. I have a macro to reposition the window every time it opens. And it happens in other os versions, not just Tahoe. It goes way back, especially when you have it on a second screen or in a space. This used to affect other apps too, but Music is probably the only ancient app left at this point.
